SPECIFCATIQN forming part of Letters Patent No. 657,245, datedsepternber 4, 1900. Application filed February 15, 1900, SorialNo. 5,312. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, LEROY J. LINDSAY, a citizen of the United States, residing at Seymour, in the county of 4Wayne and State of Iowa, have invented a new and useful Automatic Check-Row Corn-Planter, of which the following is a specification.

My object is to provide an automatic cornplanter specially adapted for different kinds and conditions of ground in which seeds are to be dropped at regular intervals of time and space as required to simultaneously plant two rows as required to produce check-rows.

My invention consists in the construction, arrangement, and combination of elements and subcombinations, as hereinafter s'et forth, pointed out in my claims, and illustrated in the accompanying drawings, in which-- Figure lis atop view of the carriage-frame and an auxiliary frame pivotally connected with each other and the runners as required to allow lateral motion and also vertical motion relative to the carriage axle and the `frame to which runners are fixed. Fig. 2 is a longitudinal sectional View, showing the manner of connecting the frames with the carriage-axle. Fig. 3 shows a clutch,a ratchetwheel, two sprocket-wheels, a coiled spring, and fixed collars connected with lthe rot-atable carriage-axle. Fig. i is a top View ofthe machine, showing the relative positions of all the operative parts. Fig. 5 is a vertical longitudinal sectional View on the line oc @o of Fig. Ll. Fig. G is a transverse sectional view, and Fig. Z a side View, of the internallytoothed ratchet-wheel and a plurality of pawls connected with the rotatable carriage-axle for transmitting motion from the carriageaxle to the rotatable axle of a marker to regulate the speed of seed-dropping mechanism as required to maintain equal distances between the points where seeds are planted in the parallel rows.

The letter A designates the rotatable carriage-axle, to which one traction-wheel A2 is lixed by keying or in any suitable way, and ,A3 a mating wheel mounted loosely on the other end of the axle.

Al represents the parallel side pieces of the carriage-frame, preferably made of lat metal bars and provided with fixed bearers A5, through which the axle A is extended'in such a manner as to allow lateral motion to the carriage-frame relative to the axle and line of advance when the planter is in operation. Sleeves Aion the axle A on the opposite sides of the bearers A5 restrict the lateral lnotions of the side bars A4. The rear ends of the bars A4 are connected by means of a rock-shaft B, mounted in bearings formed in or iixed to said ends. The end portions of the rockshaft are bent laterally, as indicated by full lines in Fig. 4, and adapt-ed to serve as wheel- Scrapers.

B2 is the frame, to which mating runners B3 are fixed. The rear cross bar or bench B4, adapted for supporting seedboxes, (not shown,) has fixed hinge members B5, to which the front ends of the side bars A4 of the carriage-frame are hinged to allow vertical motion to the runners.

The auxiliary frame is composed of two mating side bars C, preferably made of angleiron, and a cross-bar C2 at their rear ends. The mating bars C have elongated openings, as clearly shown in Fig. 2, through which the carriage-axle A is extended, and rollers CB on the axle A facilitate the lateral motions of the auxiliary frame relative to the carriageframe and line of advance, as required to reduce friction.

C'1 is a rock-shaft in bearings formed in or fixed to the front ends of the mating side bars C. It has a central enlargement and a bore in said enlargement and is pivotally connected with the cross-bar BIl of the runnerframe by meansyof a yoke C5, fixed to said bar, and a pin C6, that has an arm Ol, adapting it to serve as a lever for raising and lowering the runners relative to the carriageframe.

D is a rock-shaft in bearings fixed to the bars C.

D2 is an arm fixed to the central portion of the shaft D andlpivotally connected with the rear endof the arm Clot the pin C by means' lof a link D3.

D4 isa hand-lever pivoted to the rock-shaft D and carries a pawl adapted to engage a toothed sector D5, that is iixed to the shaft at the side of said hand-lever in such a manner that the rock-shaft can be retained in a fixed position, as required, to govern the depth of furrow made by the heels of the runners B2.

D6 is a rearward extension of the arm D2 for engaging and actuating a clutch-operating device.

F is a seat-support connected with the roekshaf't D and the cross-bar C2 ot` the auxiliary frame.

F2 is a clutch member fixed to the carriageaxle A2.

F3 is a clutch member slidingly connected with the axle A.

F4 is a cluteh-moving arm pivoted to the cross-bar C2 of the auxiliary frame and its bifurcated frontend strides the sliding clutch member F3.

F5 is an extension formed on or fixed to the arm F4 and projects laterally to serve as a cam that is engaged by the rear extension D6 of the arm D2 in such a manner that a rearward motion of the hand-lever D4 will, by means of a cam on the arm F4, disengage the sliding clutch member FS from the fixed Incinber F2 on the axle A. i H is an internally-toothed ratchet-wheel formed .on or'fixed to the sliding clutch member F2.

A pawl-carrier is fixed to the end of the sleeve H2 on the axle A.

H3 and H4 are sprocket-wheels fixed to the slid-ing hub or sleeve H2.

H5 is a collar fixed to the axle A.

H6 is a compressible coil-spring placed on `the axle A between the fixed collar and the slidingr hub or sleeve H2 in such a manner that the spring will in its normal condition retain the sliding clutch member F3 in engagement with the fixed member F2, as required to rotate the ratchet-wheel H and the two sprocket-wheels H2 and H4 jointly and at equal speed with axle A.

J is a rock-shaft in bearings fixed to the side bars C of the auxiliary frame.

J2 is a shaft-bearer on the lower free end of an arm J2, fixed to the central portion of the rock-shaft J.

J4 is a rotatable shaft in the bearer J2, and J 5 represents mating markers fixed to the ends of the shaft to engage the ground as the carriage is advanced and the axle A rotated. The shaft J4 is twice as long as the space between the runners B2, so that in a return trip across a field the marker on one end of the shaft will travel over the marks or track made by the other marker, as required to maintain equal distances between parallel rows.

K is a sprocket-wheel fixed to the center of the shaft J4, and K2 a chain that connects said wheel with the sprocket-wheel H3, rotatably and slidingly connected with the axle A in such a manner that when the sliding clutch member F2 is disengaged from the fixed member F2 on the axle A ratchet-wheels H and the sprocket-wheels H2 and H4 will be idle on the axle A to facilitate regulating the space between seeds dropped in the furrows made by the heels of the runners B3 whenever such space becomes irregular or increased by the slipping of the fixed wheel A2 on the axle A, that rotates said axle. result is accomplished by means of the pawls l on the pawl-carrier H2 coming into engagement with the internal teeth of the ratchetwheel H, that is xed to the clutch member F2, whenever the lever D4 is operated to disengage the sliding clutch member from the fixed member F2 on the axle A.

M is a lever on the end of the rock-shaft J, and M2 a rack fixed on one of the bars C of the auxiliaryvframe, as shown in Fig. 4, in such a manner that the axle J4, carrying the markers on its ends, can be raised and lowered thereby, as required, to regulate the grip of the markers with the ground and to make the sprocket-wheels Hs and H4 on the axle A and the seeddropping mechanism connected therewith inoperative when turning the machine about or for regulating the space between the points where the seeds are dropped.

N is a rotatable shaft in bearings fixed to the cross-bar B4 for communicating motion to seed -dropping mechanism in the seedboxes (not shown) designed to be supported at the ends of said cross-bar. The shaft N has a fixed sprocket-wheel N2 at its center, and a chain N3 connects it with the wheel H4 on the axle A.

Pis a lever connected with the end portion of the rock-shaft B and provided with hooks P2 and P2, adapted in shape at its free end to hook over the axle A, as required to retain the scrapers on the ends of the shaft inoperative, as shown in Figs. 4E and 5, or in engagement with carriage-wheels.

Having described the construction and function of each element and subcombination of my invention, its practical operation and utility will be understood by persons familiar with the art to which it pertains.

What I claim as new, and desire to secure by Letters Patent, is
